Description

本発明は、樹脂構造体に関する。 The present invention relates to a resin structure.

従来から、車両に搭載されるリレーボックス(電気接続箱)等のように、複数の樹脂体を互いに組み付けて構成される樹脂構造体が広く知られている(例えば、特許文献1を参照)。 Conventionally, a resin structure composed of a plurality of resin bodies assembled with each other, such as a relay box (electrical connection box) mounted on a vehicle, is widely known (see, for example, Patent Document 1).

特開2017−022824号公報JP-A-2017-022824

ところで、上述したような樹脂構成体を構成する際、例えば、第1樹脂体の外面に沿って第2樹脂体をスライドさせながら第2樹脂体を第1樹脂体の外面に組み付ける場合がある。このような組み付けに対応した構造を有する樹脂構造体において、第1樹脂体と第2樹脂体との組付箇所を止水するべく、例えば、双方の樹脂体とを互いに押圧接触させた状態で組み付ける場合がある。この場合、止水性を高めるために双方の樹脂体をより強固に密着させようとすると、通常、その分だけ第2樹脂体を第1樹脂体に押し込むために要する力が大きくなり、作業性が低下する傾向がある。換言すると、双方の樹脂体の間の止水性と、双方の樹脂体を組み付ける際の作業性と、の両立が困難である。 By the way, when constructing the resin structure as described above, for example, the second resin body may be assembled to the outer surface of the first resin body while sliding the second resin body along the outer surface of the first resin body. In a resin structure having a structure corresponding to such assembly, in order to stop water at the assembly portion between the first resin body and the second resin body, for example, both resin bodies are in pressure contact with each other. It may be assembled. In this case, if both resin bodies are to be brought into close contact with each other in order to improve the water stopping property, the force required to push the second resin body into the first resin body is usually increased by that amount, and the workability is improved. Tends to decline. In other words, it is difficult to achieve both water-stopping between both resin bodies and workability when assembling both resin bodies.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、第1樹脂体の外面に沿って第2樹脂体をスライドさせながら第2樹脂体を第1樹脂体の外面に組み付ける際の作業性と、第1樹脂体と第2樹脂体との組付箇所の止水性とを両立可能な樹脂構造体を提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to assemble the second resin body to the outer surface of the first resin body while sliding the second resin body along the outer surface of the first resin body. It is an object of the present invention to provide a resin structure capable of achieving both workability at the time and water blocking of a portion where the first resin body and the second resin body are assembled.

The waterproof structure is
In the first region, a second water stop plate provided in the other resin body extending in the slide direction is inserted into the second groove portion provided in the one resin body extending in the slide direction. , Has a third waterproof structure,
Must be a resin structure.

上記[1]の構成の樹脂構造体によれば、第2樹脂体が第1樹脂体に組み付けられた状態において、第1樹脂体及び第2樹脂体の協働により、スライド方向に延びる止水構造部が構成される。止水構造部におけるスライド方向の一方側(即ち、第2樹脂体を組み付けるときのスライド方向前方側)に位置する第1領域では、止水面に押圧接触する止水リブ(以下「押圧接触による第1止水構造」という。)により止水機能が発揮される。止水構造部におけるスライド方向の他方側(即ち、第2樹脂体を組み付けるときのスライド方向後方側)に位置する第2領域では、第1溝部に第1止水板を進入させて水の進入経路(いわゆる沿面距離)を長くするラビリンス構造(以下「沿面距離の確保による第2止水構造」という。)により止水機能が発揮される。 According to the resin structure having the configuration of [1] above, in a state where the second resin body is assembled to the first resin body, the water stoppage extending in the sliding direction is caused by the cooperation of the first resin body and the second resin body. The structural part is composed. In the first region located on one side of the water-stopping structure in the sliding direction (that is, the front side in the sliding direction when the second resin body is assembled), the water-stopping ribs that press-contact the water-stopping surface (hereinafter, "the first by pressing contact"). The water-stopping function is exhibited by the "1 water-stopping structure"). In the second region located on the other side of the water stop structure portion in the slide direction (that is, the rear side in the slide direction when the second resin body is assembled), the first water stop plate is made to enter the first groove portion to allow water to enter. A labyrinth structure that lengthens the route (so-called creepage distance) (hereinafter referred to as "second water stop structure by securing the creepage distance") exerts a water stop function.

一般に、沿面距離の確保による第2止水構造を採用する場合、押圧接触による第1止水構造を採用する場合と比べて、水の進入経路(沿面距離)が長くなることから、第1樹脂体と第2樹脂体との組付箇所の止水性が高くなる。一方、沿面距離の確保による第2止水構造を採用する場合、第1溝部に第1止水板を進入させるために双方の樹脂体の相対位置及び相対姿勢を調整する作業が必要となり、作業性を向上させ難い。逆に、押圧接触による第1止水構造を採用する場合、沿面距離の確保による第2止水構造を採用する場合と比べ、双方の樹脂体を組み付ける際の作業性を向上させ易い。 In general, when the second water blocking structure for securing the creepage distance is adopted, the water entry path (creeping distance) is longer than when the first water stopping structure for pressing contact is adopted, so that the first resin is used. The water stoppage of the assembly point between the body and the second resin body is increased. On the other hand, when adopting the second water stop structure by securing the creepage distance, it is necessary to adjust the relative position and the relative posture of both resin bodies in order to allow the first water stop plate to enter the first groove portion. It is difficult to improve the sex. On the contrary, when the first water blocking structure by pressing contact is adopted, the workability when assembling both resin bodies is easily improved as compared with the case where the second water stopping structure by securing the creepage distance is adopted.

更に、スライド方向の一方側(前方側。奥側)に押圧接触による第1止水構造を採用することで、スライド方向の一方側(前方側。奥側)に沿面距離の確保による第2止水構造を採用する場合に比べ、第1樹脂体に第2樹脂体を組み付け易くなり(例えば、押し込み易くなり)、双方の樹脂体を組み付ける際の作業性を向上させ易い。 Furthermore, by adopting the first water stop structure by pressing contact on one side (front side, back side) of the slide direction, the second stop by securing the creepage distance on one side (front side, back side) of the slide direction. Compared with the case of adopting the water structure, it becomes easier to assemble the second resin body to the first resin body (for example, it becomes easier to push in), and it is easy to improve the workability when assembling both resin bodies.

以上から、本構成の樹脂構造体は、第1樹脂体の外面に沿って第2樹脂体をスライドさせながら第2樹脂体を第1樹脂体の外面に組み付ける際の作業性と、第1樹脂体と第2樹脂体との組付箇所の止水性とを両立可能である。 From the above, the resin structure having the present configuration has workability when assembling the second resin body to the outer surface of the first resin body while sliding the second resin body along the outer surface of the first resin body, and the first resin. It is possible to achieve both water-stopping at the assembly point between the body and the second resin body.

上記[2]の構成の樹脂構造体によれば、止水性が相対的に低くなり易い押圧接触による第1止水構造を採用する第1領域に、第2溝部及び第2止水板による第3止水構造が追加される。この結果、止水構造部の第1領域の止水性が向上し、止水構造部の全体における止水性を更に高めることができる。 According to the resin structure having the configuration of the above [2], the second groove portion and the second water stop plate are provided in the first region where the first water stop structure by the pressing contact where the water stoppage tends to be relatively low is adopted. 3 Water stop structure is added. As a result, the water-stopping property of the first region of the water-stopping structure portion is improved, and the water-stopping property of the entire water-stopping structure portion can be further enhanced.

このように、本発明によれば、第1樹脂体の外面に沿って第2樹脂体をスライドさせながら第2樹脂体を第1樹脂体の外面に組み付ける際の作業性と、第1樹脂体と第2樹脂体との組付箇所の止水性とを両立可能な樹脂構造体を提供できる。 As described above, according to the present invention, workability when assembling the second resin body to the outer surface of the first resin body while sliding the second resin body along the outer surface of the first resin body, and the first resin body. It is possible to provide a resin structure capable of achieving both water-stopping of the assembly portion between the second resin body and the second resin body.

<実施形態>
以下、図面を参照しながら、図1に示す本発明の実施形態に係る樹脂構造体1について説明する。樹脂構造体1は、典型的には、車両に搭載され、リレー等の電子部品を収容するリレーボックス(電気接続箱)である。樹脂構造体1の車両搭載時において、図1における手前側(図1における左下側)及び奥側(図1における右上側)は、それぞれ、車両の前側及び後側に対応している。
<Embodiment>
Hereinafter, the resin structure 1 according to the embodiment of the present invention shown in FIG. 1 will be described with reference to the drawings. The resin structure 1 is typically a relay box (electrical connection box) mounted on a vehicle and accommodating electronic components such as relays. When the resin structure 1 is mounted on the vehicle, the front side (lower left side in FIG. 1) and the back side (upper right side in FIG. 1) in FIG. 1 correspond to the front side and the rear side of the vehicle, respectively.

図1及び図2に示すように、樹脂構造体1は、フレーム2と、フレーム2の車両前側の上方に組み付けられる第1フロントカバー3及び第2フロントカバー4と、フレーム2の車両後側領域の上端開口を塞ぐようにフレーム2の上方に組み付けられる第1アッパカバー5と、フレーム2の車両前側領域及び第1フロントカバー3の上端開口を塞ぐようにフレーム2及び第1フロントカバー3の上方に組み付けられる第2アッパカバー6と、フレーム2の車両前側の下方に組み付けられるアンダカバー7と、フレーム2及びアンダカバー7の下端開口を塞ぐようにフレーム2及びアンダカバー7の下方に組み付けられるロアカバー8と、フレーム2の車両左右方向における一方側の外面(側面)に組み付けられるサイドカバー9と、により構成される。樹脂構造体1を構成する上記8つの部品は全て、樹脂成形体である。 As shown in FIGS. 1 and 2, the resin structure 1 includes a frame 2, a first front cover 3 and a second front cover 4 assembled above the vehicle front side of the frame 2, and a vehicle rear side region of the frame 2. The first upper cover 5 assembled above the frame 2 so as to close the upper end opening of the frame 2, and above the frame 2 and the first front cover 3 so as to close the vehicle front side region of the frame 2 and the upper end opening of the first front cover 3. The second upper cover 6 to be assembled to, the undercover 7 to be attached to the lower part of the front side of the vehicle of the frame 2, and the lower cover to be attached to the lower part of the frame 2 and the undercover 7 so as to close the lower end openings of the frame 2 and the undercover 7. 8 and a side cover 9 attached to the outer surface (side surface) of one side of the frame 2 in the left-right direction of the vehicle. The above eight parts constituting the resin structure 1 are all resin molded bodies.

図2に示すように、フレーム2の内部、並びに、第1フロントカバー3(及び第2フロントカバー4)の内部には、リレー等の電子部品(及び、その他の部品)Rが収容されている。本発明は、樹脂構造体1のうち、フレーム2、及び、サイドカバー9の構造に係る。よって、以下、フレーム2、及び、サイドカバー9のみの構造について詳細に説明する。 As shown in FIG. 2, electronic components (and other components) R such as relays are housed inside the frame 2 and inside the first front cover 3 (and the second front cover 4). .. The present invention relates to the structure of the frame 2 and the side cover 9 of the resin structure 1. Therefore, the structure of only the frame 2 and the side cover 9 will be described in detail below.

以下、説明の便宜上、図3に示すように、「内外方向」、「幅方向」、「上下方向」、「内」、「外」、「上」及び「下」を定義する。「内外方向」、「幅方向」及び「上下方向」は、互いに直交している。樹脂構造体1の車両搭載時において、「内外方向」、「幅方向」及び「上下方向」は、それぞれ、車両の左右方向、車両前後方向及び車両上下方向に対応している。 Hereinafter, for convenience of explanation, as shown in FIG. 3, "inside / outside direction", "width direction", "vertical direction", "inside", "outside", "top" and "bottom" are defined. The "inside / outside direction", "width direction", and "vertical direction" are orthogonal to each other. When the resin structure 1 is mounted on a vehicle, the "inside / outside direction", "width direction", and "vertical direction" correspond to the left-right direction of the vehicle, the front-rear direction of the vehicle, and the up-down direction of the vehicle, respectively.

サイドカバー9は、フレーム2の外面に沿って下向きにスライドさせることで、フレーム2の外面に組み付けられるようになっている。よって、「上下方向」は、サイドカバー9のスライド方向に対応している。フレーム2の外面に組み付けられたサイドカバー9と、フレーム2の内面との間に画成される空間は、典型的には、端子などの部品(図示省略)を収容するための空間として使用される。 The side cover 9 can be attached to the outer surface of the frame 2 by sliding it downward along the outer surface of the frame 2. Therefore, the "vertical direction" corresponds to the sliding direction of the side cover 9. The space defined between the side cover 9 assembled on the outer surface of the frame 2 and the inner surface of the frame 2 is typically used as a space for accommodating parts such as terminals (not shown). To.

先ず、フレーム2について説明する。図1〜図5に示すように、フレーム2は、樹脂構造体1の側面の外観の大部分を構成する。フレーム2におけるサイドカバー9が組み付けられる箇所には、図3〜図5に示すように、フレーム2の外面にて、幅方向に離間して幅方向に互いに向かい合う一対の対向面11が形成されている。サイドカバー9の組付時、一対の対向面11には、サイドカバー9の後述する一対の端縁部31(図6等参照)が押圧接触することになる。 First, the frame 2 will be described. As shown in FIGS. 1 to 5, the frame 2 constitutes most of the appearance of the side surface of the resin structure 1. As shown in FIGS. 3 to 5, a pair of facing surfaces 11 that are separated from each other in the width direction and face each other in the width direction are formed on the outer surface of the frame 2 at a position where the side cover 9 is assembled in the frame 2. There is. When the side cover 9 is assembled, the pair of end edge portions 31 (see FIG. 6 and the like) of the side cover 9, which will be described later, come into pressure contact with the pair of facing surfaces 11.

図5に示すように、一対の対向面11のそれぞれは、下側に向かうにつれて両者の間隔が徐々に狭くなるように、上下方向に対して角度θだけ傾斜して延びる平面である。角度θは、型を用いて樹脂成形体を成形する際において型抜き性を高めるために通常設けられる所謂「抜き勾配」より大きい値である。別の言い方をすると、一般の抜き勾配よりも大きな角度θだけ傾くように意図的に設計された一対の対向面11は、通常は抜き勾配に相当する角度程度の傾きしか有さない(実質的には、上下方向に平行といえる)一対の止水板25(図8等を参照)よりも、大きく傾いている。この角度θは、組み付けの作業性や止水性などを考慮して定められればよく、特に制限されないが、一例として3度以上5度以下である。 As shown in FIG. 5, each of the pair of facing surfaces 11 is a plane that extends at an angle θ with respect to the vertical direction so that the distance between the two faces gradually narrows toward the lower side. The angle θ is a value larger than the so-called “drawing gradient” usually provided to improve the die-cutting property when molding the resin molded product using the mold. In other words, a pair of facing surfaces 11 intentionally designed to incline by an angle θ larger than a general draft, usually have an inclination of only an angle corresponding to the draft (substantially). Is more inclined than the pair of water stop plates 25 (see FIG. 8 and the like) (which can be said to be parallel in the vertical direction). This angle θ may be determined in consideration of assembly workability, water stopping property, etc., and is not particularly limited, but is, for example, 3 degrees or more and 5 degrees or less.

本例では、止水性向上のため、一対の対向面11から連続してフレーム2の外面から更に外側に突出する一対の止水板11a,11bが設けられている。図3及び図4から理解できるように、本例では、一対の止水板11a,11bのうち、図3及び図4における右側(車両前側に相当)の止水板11aは、対応する対向面11の上下方向全域に亘って設けられているが、図3及び図4における左側(車両後側に相当)の止水板11bは、対応する対向面11の上下方向の下側領域のみに設けられている。これは、車両前方からの水の浸入をより確実に防止する、という思想に基づく。 In this example, in order to improve the water stopping property, a pair of water stopping plates 11a and 11b are provided continuously from the pair of facing surfaces 11 and further projecting outward from the outer surface of the frame 2. As can be understood from FIGS. 3 and 4, in this example, of the pair of water stop plates 11a and 11b, the water stop plate 11a on the right side (corresponding to the front side of the vehicle) in FIGS. Although it is provided over the entire vertical direction of 11, the water stop plate 11b on the left side (corresponding to the rear side of the vehicle) in FIGS. 3 and 4 is provided only in the lower region of the corresponding facing surface 11 in the vertical direction. Has been done. This is based on the idea of more reliably preventing the ingress of water from the front of the vehicle.

フレーム2の外面における一対の対向面11の間の領域には、内側に窪むと共に上下方向に延びる部品収容部12が設けられている。部品収容部12は、一対の対向面11の上下方向全域に対応して、上下方向に延びている。部品収容部12は、端子などの部品を収容するための空間の一部として使用されることになる。 In the region between the pair of facing surfaces 11 on the outer surface of the frame 2, a component accommodating portion 12 that is recessed inward and extends in the vertical direction is provided. The component accommodating portion 12 extends in the vertical direction corresponding to the entire vertical direction of the pair of facing surfaces 11. The component accommodating portion 12 will be used as a part of a space for accommodating components such as terminals.

部品収容部12の下端部には、部品収容部12と上下方向に連通するように、内側に窪むと共に上下方向に延びる電線収容部13が設けられている。電線収容部13は、端子などの部品から下方に延出する電線を収容するための空間の一部として使用されることになる。 At the lower end of the component accommodating portion 12, an electric wire accommodating portion 13 that is recessed inward and extends in the vertical direction is provided so as to communicate with the component accommodating portion 12 in the vertical direction. The electric wire accommodating portion 13 will be used as a part of a space for accommodating an electric wire extending downward from a component such as a terminal.

部品収容部12の幅方向両側部には、部品収容部12の幅方向両側内壁面から連続してフレーム2の外面から外側に突出すると共に上下方向に延びる一対の止水板14が設けられている(図10及び図11も参照)。一対の止水板14は、部品収容部12(即ち、一対の対向面11)の上下方向全域に対応して、上下方向に延びている。 A pair of water blocking plates 14 are provided on both sides of the component accommodating portion 12 in the width direction so as to continuously project outward from the outer surface of the frame 2 and extend in the vertical direction from the inner wall surfaces on both sides in the width direction of the component accommodating portion 12. (See also FIGS. 10 and 11). The pair of water stop plates 14 extend in the vertical direction corresponding to the entire vertical direction of the component accommodating portion 12 (that is, the pair of facing surfaces 11).

部品収容部12の内部には、一対の止水板14から幅方向内側に所定距離だけ離れた位置にて、一対の止水板15が設けられている。一対の止水板15は、一対の止水板14の下側領域のみに対応して、部品収容部12の底面から外側に突出して上下方向に延びている。この結果、一対の止水板14と一対の止水板15との間には、一対の止水板14の下側領域にて、外側に開口し上下方向に延びる一対の溝16が形成されている(図11も参照)。 Inside the component accommodating portion 12, a pair of water stop plates 15 are provided at positions separated from the pair of water stop plates 14 inward by a predetermined distance in the width direction. The pair of water stop plates 15 project outward from the bottom surface of the component accommodating portion 12 and extend in the vertical direction, corresponding only to the lower region of the pair of water stop plates 14. As a result, between the pair of water stop plates 14 and the pair of water stop plates 15, a pair of grooves 16 that open outward and extend in the vertical direction are formed in the lower region of the pair of water stop plates 14. (See also FIG. 11).

一対の対向面11と一対の止水板14との間における一対の止水板14の下側領域には、上方に向けて突出する一対の係止片17が、一対の止水板14と一体で設けられている。一対の係止片17は、サイドカバー9の組付時、サイドカバー9の後述する一対の係止部29の貫通孔29aに挿入されることになる。 In the lower region of the pair of water stop plates 14 between the pair of facing surfaces 11 and the pair of water stop plates 14, a pair of locking pieces 17 projecting upward are formed with the pair of water stop plates 14. It is provided integrally. When the side cover 9 is assembled, the pair of locking pieces 17 are inserted into the through holes 29a of the pair of locking portions 29 described later in the side cover 9.

次いで、サイドカバー9について説明する。図6〜図9に示すように、サイドカバー9は、略矩形平板状の平板部21を備える。平板部21の幅方向中央部には、外側に突出すると共に上下方向に延びる隆起部22が形成されている。隆起部22は、平板部21の下端縁から更に下方に延びている。隆起部22の内面側には、図8及び図9に示すように、外側に窪むと共に上下方向に延びる部品収容部23が形成されている。部品収容部23の下端部には、上下方向に貫通する一対の水抜き孔23aが形成されている(図8及び図11を参照)。 Next, the side cover 9 will be described. As shown in FIGS. 6 to 9, the side cover 9 includes a substantially rectangular flat plate portion 21. A raised portion 22 that projects outward and extends in the vertical direction is formed in the central portion of the flat plate portion 21 in the width direction. The raised portion 22 extends further downward from the lower end edge of the flat plate portion 21. As shown in FIGS. 8 and 9, a component accommodating portion 23 that is recessed outward and extends in the vertical direction is formed on the inner surface side of the raised portion 22. A pair of drain holes 23a penetrating in the vertical direction are formed at the lower end of the component accommodating portion 23 (see FIGS. 8 and 11).

部品収容部23の下端部には、電線収容部24が下方に突出するように連設されている。サイドカバー9の組付状態にて、部品収容部23及び電線収容部24は、それぞれ、フレーム2の部品収容部12及び電線収容部13と協働で、端子などの部品を収容するための空間及び当該部品から延出する電線を収容するための空間を画成する。 At the lower end of the component accommodating portion 23, the electric wire accommodating portion 24 is continuously provided so as to project downward. In the assembled state of the side cover 9, the parts accommodating portion 23 and the electric wire accommodating portion 24 are spaces for accommodating parts such as terminals in cooperation with the parts accommodating portion 12 and the electric wire accommodating portion 13 of the frame 2, respectively. And, a space for accommodating the electric wire extending from the relevant part is defined.

部品収容部23の幅方向両側部には、部品収容部23の幅方向両側内壁面から連続して平板部21の内面から内側に突出すると共に上下方向に延びる一対の止水板25が設けられている(図10及び図11も参照)。 A pair of water blocking plates 25 are provided on both side portions in the width direction of the component accommodating portion 23 so as to continuously project inward from the inner surface of the flat plate portion 21 and extend in the vertical direction from the inner wall surfaces on both sides in the width direction of the component accommodating portion 23. (See also FIGS. 10 and 11).

平板部21には、一対の止水板25から幅方向外側に所定距離だけ離れた位置にて、一対の止水板26が設けられている。一対の止水板26は、一対の止水板25の上側領域のみに対応して、平板部21の内面から内側に突出して上下方向に延びている。一対の止水板26は、平板部21の下端縁まで下方に延びている。この結果、一対の止水板25と一対の止水板26との間には、一対の止水板25の上側領域にて、内側に開口し上下方向に延びる一対の溝27が形成されている(図10も参照)。 The flat plate portion 21 is provided with a pair of water stop plates 26 at positions separated from the pair of water stop plates 25 by a predetermined distance outward in the width direction. The pair of water stop plates 26 project inward from the inner surface of the flat plate portion 21 and extend in the vertical direction, corresponding only to the upper region of the pair of water stop plates 25. The pair of water stop plates 26 extend downward to the lower end edge of the flat plate portion 21. As a result, between the pair of water stop plates 25 and the pair of water stop plates 26, a pair of grooves 27 that open inward and extend in the vertical direction are formed in the upper region of the pair of water stop plates 25. (See also FIG. 10).

一対の止水板25の幅方向外側面における一対の止水板26より下方の領域には、幅方向外側に突出し且つ上下方向に延びる一対の止水リブ28が形成されている(図11も参照)。 In the region below the pair of water stop plates 26 on the outer surface of the pair of water stop plates 25 in the width direction, a pair of water stop ribs 28 projecting outward in the width direction and extending in the vertical direction are formed (also in FIG. 11). reference).

平板部21の幅方向両側の下端部の外面側には、平板部21の下端縁から下方に延びるように、一対の係止部29が、一対の止水板25と一体で設けられている。一対の係止部29には、上下方向に貫通する一対の貫通孔29aが形成されている。 On the outer surface side of the lower end portions on both sides of the flat plate portion 21 in the width direction, a pair of locking portions 29 are provided integrally with the pair of water blocking plates 25 so as to extend downward from the lower end edge of the flat plate portion 21. .. A pair of through holes 29a penetrating in the vertical direction are formed in the pair of locking portions 29.

サイドカバー9の幅方向両側の一対の端縁部31は、平板部21の幅方向両側の一対の端縁部及び一対の係止部29の幅方向両側の一対の端縁部により構成されている(特に、図6及び図8参照)。一対の端縁部31のそれぞれは、フレーム2の一対の対向面11と同様、下側に向かうにつれて両者の間隔が徐々に狭くなるように、上下方向に対して角度θだけ傾斜して延びる平面である。以上、フレーム2、及び、サイドカバー9の構造について説明した。 The pair of edge portions 31 on both sides of the side cover 9 in the width direction are composed of a pair of edge portions on both sides in the width direction of the flat plate portion 21 and a pair of edge portions on both sides in the width direction of the pair of locking portions 29. (In particular, see FIGS. 6 and 8). Like the pair of facing surfaces 11 of the frame 2, each of the pair of edge portions 31 is a plane that extends at an angle θ with respect to the vertical direction so that the distance between the two ends gradually narrows toward the lower side. Is. The structures of the frame 2 and the side cover 9 have been described above.

次いで、フレーム2にサイドカバー9を組み付ける際の手順について説明する。フレーム2にサイドカバー9を組み付ける際には、サイドカバー9を、フレーム2におけるサイドカバー9が組み付けられる箇所の上方に近づけ、サイドカバー9の一対の端縁部31の下端部を、フレーム2の一対の対向面11の上端部と幅方向に対面させる。 Next, a procedure for assembling the side cover 9 to the frame 2 will be described. When assembling the side cover 9 to the frame 2, the side cover 9 is brought close to the upper part of the frame 2 where the side cover 9 is to be assembled, and the lower ends of the pair of end edge portions 31 of the side cover 9 are attached to the frame 2. It faces the upper ends of the pair of facing surfaces 11 in the width direction.

この状態では、幅方向において、サイドカバー9の一対の止水板25とフレーム2の一対の溝16との位置が一致し(図11参照)、且つ、フレーム2の一対の止水板14とサイドカバー9の一対の溝27との位置が一致している(図10参照)。更に、サイドカバー9の一対の係止部29の貫通孔29aとフレーム2の一対の係止片17とが上下方向において同軸的に位置している。 In this state, the positions of the pair of water stop plates 25 of the side cover 9 and the pair of grooves 16 of the frame 2 coincide with each other in the width direction (see FIG. 11), and the pair of water stop plates 14 of the frame 2 and the pair of water stop plates 14 The positions of the side cover 9 with the pair of grooves 27 are the same (see FIG. 10). Further, the through holes 29a of the pair of locking portions 29 of the side cover 9 and the pair of locking pieces 17 of the frame 2 are coaxially positioned in the vertical direction.

次いで、この状態から、サイドカバー9をフレーム2に対して下向きにスライドさせる。この過程において、サイドカバー9の一対の止水板25がフレーム2の一対の溝16に上方から進入し、フレーム2の一対の止水板14がサイドカバー9の一対の溝27に上方から進入していく。また、一対の端縁部31及び一対の対向面11の双方が、下側に向かうにつれて間隔が徐々に狭くなるように上下方向に対して角度θだけ傾斜しているため、一対の端縁部31及び一対の対向面11の間隔が次第に狭くなっていく。また、一対の係止片17が一対の貫通孔29aに挿入される。 Next, from this state, the side cover 9 is slid downward with respect to the frame 2. In this process, the pair of water stop plates 25 of the side cover 9 enter the pair of grooves 16 of the frame 2 from above, and the pair of water stop plates 14 of the frame 2 enter the pair of grooves 27 of the side cover 9 from above. I will do it. Further, since both the pair of edge portions 31 and the pair of facing surfaces 11 are inclined by an angle θ with respect to the vertical direction so that the interval gradually narrows toward the lower side, the pair of edge portions 31 The distance between the 31 and the pair of facing surfaces 11 gradually becomes narrower. Further, the pair of locking pieces 17 are inserted into the pair of through holes 29a.

そして、サイドカバー9が組付完了位置に到達すると、一対の係止片17が一対の貫通孔29aに係止される。加えて、一対の端縁部31が、一対の対向面11対して、それぞれ(平面で)接触し、且つ、所謂くさび効果により押圧された状態に維持される。このため、フレーム2とサイドカバー9との間の相対移動(ガタ)の発生が効果的に抑制され得る。更には、一対の端縁部31が一対の対向面11にそれぞれ(平面で)押圧接触することで、一対の端縁部31及び一対の対向面11の接触部を介する水の浸入を効果的に抑制することができる。 Then, when the side cover 9 reaches the assembly complete position, the pair of locking pieces 17 are locked in the pair of through holes 29a. In addition, the pair of edge portions 31 are kept in contact with the pair of facing surfaces 11 (in a plane) and pressed by the so-called wedge effect. Therefore, the occurrence of relative movement (play) between the frame 2 and the side cover 9 can be effectively suppressed. Further, by pressing and contacting the pair of edge portions 31 with each other (in a plane), it is effective to allow water to enter through the contact portions of the pair of edge portions 31 and the pair of facing surfaces 11. Can be suppressed.

更に、サイドカバー9の組付完了状態では、図10に示すように、フレーム2の一対の止水板14の上側領域が、サイドカバー9の一対の溝27に進入している。また、図11に示すように、サイドカバー9の一対の止水板25の下側領域が、フレーム2の一対の溝16に進入し、且つ、サイドカバー9の一対の止水リブ28が、フレーム2の一対の止水板14の幅方向内側面の下側領域にそれぞれ押圧接触している。このように、サイドカバー9の組付完了状態では、上下方向に延びる一対の「止水構造部」が構成されている。 Further, in the assembled state of the side cover 9, as shown in FIG. 10, the upper region of the pair of water stop plates 14 of the frame 2 has entered the pair of grooves 27 of the side cover 9. Further, as shown in FIG. 11, the lower region of the pair of water stop plates 25 of the side cover 9 enters the pair of grooves 16 of the frame 2, and the pair of water stop ribs 28 of the side cover 9 are formed. Each of the pair of water stop plates 14 of the frame 2 is in pressure contact with the lower region of the inner side surface in the width direction. As described above, in the assembled state of the side cover 9, a pair of "water-stopping structure portions" extending in the vertical direction are configured.

一対の止水構造部の下側領域(第1領域)では、図11に示すように、一対の止水板14の幅方向内側面に押圧接触する一対の止水リブ28(押圧接触による第1止水構造)により止水機能が発揮される。また、一対の「止水構造部」の上側領域(第2領域)では、図10に示すように、溝27に止水板14を進入させて水の進入経路(沿面距離)を長くするラビリンス構造(沿面距離の確保による第2止水構造)により止水機能が発揮される。 In the lower region (first region) of the pair of water-stopping structures, as shown in FIG. 11, a pair of water-stopping ribs 28 (third by pressure-contacting) that press-contact with the inner side surfaces of the pair of water-stopping plates 14 in the width direction. (1) Water-stopping structure) provides a water-stopping function. Further, in the upper region (second region) of the pair of "water-stopping structures", as shown in FIG. 10, a labyrinth in which the water-stopping plate 14 is made to enter the groove 27 to lengthen the water entry path (creeping distance). The water-stopping function is exhibited by the structure (second water-stopping structure by securing the creepage distance).

一般に、沿面距離の確保による第2止水構造を採用する場合、押圧接触による第1止水構造を採用する場合と比べて、水の進入経路(沿面距離)が長くなることから、止水構造部の止水性が高くなる。一方、沿面距離の確保による第2止水構造を採用する場合、溝部に止水板を進入させるためにフレーム2及びサイドカバー9の相対位置及び相対姿勢を調整する作業が必要となり、サイドカバー9のフレーム2への組み付け性が低下し易い。逆に、押圧接触による第1止水構造を採用する場合、沿面距離の確保による第2止水構造を採用する場合と比べて、サイドカバー9のフレーム2への組み付け性が高くなる。更に、止水構造部の下側領域に押圧接触による第1止水構造を採用する場合の方が、その下側領域に沿面距離の確保による第2止水構造を採用する場合と比べ、フレーム2にサイドカバー9を押し込み易くなり、サイドカバー9のフレーム2への組み付け性を向上させ易い。 In general, when the second water stop structure by securing the creepage distance is adopted, the water entry path (creeping distance) is longer than when the first water stop structure by pressure contact is adopted, so that the water stop structure The water stoppage of the part becomes high. On the other hand, when adopting the second water stop structure by securing the creepage distance, it is necessary to adjust the relative position and the relative posture of the frame 2 and the side cover 9 in order to allow the water stop plate to enter the groove, and the side cover 9 Is likely to be less easily assembled to the frame 2. On the contrary, when the first water stop structure by pressing contact is adopted, the assembling property of the side cover 9 to the frame 2 is higher than in the case of adopting the second water stop structure by securing the creepage distance. Further, the case where the first water stop structure by pressure contact is adopted in the lower region of the water stop structure portion is more the case where the second water stop structure by securing the creepage distance is adopted in the lower region, and the frame is adopted. It becomes easy to push the side cover 9 into 2, and it is easy to improve the assembling property of the side cover 9 to the frame 2.

以上のことから、上記構成によれば、止水構造部の下側領域に押圧接触による第1止水構造を採用することで、サイドカバー9のフレーム2への組み付け性を向上し、且つ、止水構造部の上側領域に第1の沿面距離の確保による第2止水構造を採用することで、止水構造部の止水性を向上させることができる。 From the above, according to the above configuration, by adopting the first water blocking structure by pressure contact in the lower region of the water stopping structure portion, the assembling property of the side cover 9 to the frame 2 is improved, and the assembling property to the frame 2 is improved. By adopting the second water-stopping structure by securing the first creepage distance in the upper region of the water-stopping structure, the water-stopping property of the water-stopping structure can be improved.

更に、一対の止水構造部の下側領域(第1領域)では、図11に示すように、上述した第1止水構造に加え、溝16に止水板25を進入させて水の進入経路(沿面距離)を長くするラビリンス構造(沿面距離の確保による第3止水構造)によっても止水機能が発揮される。 Further, in the lower region (first region) of the pair of water-stopping structures, as shown in FIG. 11, in addition to the above-mentioned first water-stopping structure, the water-stopping plate 25 is made to enter the groove 16 to allow water to enter. The water-stopping function is also exhibited by the labyrinth structure (third water-stopping structure by securing the creepage distance) that lengthens the route (creeping distance).

よって、止水性が相対的に劣り易い押圧接触による第1止水構造を採用する止水構造部の下側領域においても、沿面距離の確保による第3止水構造の併用により、止水性を更に向上できる。その結果、上下方向に延びる止水構造部の全体における止水性を更に向上できることになる。 Therefore, even in the lower region of the water-stopping structure that adopts the first water-stopping structure by pressure contact, which tends to be relatively inferior in water-stopping property, the water-stopping property is further improved by using the third water-stopping structure by securing the creepage distance. Can be improved. As a result, the water stopping property of the entire water stopping structure portion extending in the vertical direction can be further improved.
